Tata iPhone parts plant under scrutiny over pollution allegations

Tamil Nadu’s pollution regulator has issued a notice to Tata Electronics over alleged wastewater contamination of nearby farmland and groundwater, raising the possibility of regulatory action against a key supplier in Apple’s India manufacturing network.

Tata Electronics is facing regulatory scrutiny in Tamil Nadu after state pollution authorities alleged that wastewater from one of its iPhone component manufacturing facilities may have contaminated nearby agricultural land and groundwater sources.

The Tamil Nadu Pollution Control Board (TNPCB) has issued a notice to the company seeking an explanation over the alleged violations and warning that further action could be considered if compliance concerns are not adequately addressed.

The facility, located in Hosur, manufactures iPhone back panels and other components for Apple. The plant forms an important part of Apple’s expanding manufacturing ecosystem in India as the technology giant continues efforts to diversify its production footprint beyond China.

Complaints prompt multiple inspections

The regulatory action follows complaints from farmers in the surrounding area, who have reportedly raised concerns over wastewater affecting agricultural fields and open wells. In response, the TNPCB conducted a series of inspections between December 2025 and May 2026 to assess the situation.

According to findings cited in a regulatory notice, inspectors observed that wastewater from the facility was being discharged into a rainwater harvesting pond located within the factory premises. The regulator alleged that overflow from the pond subsequently reached adjoining agricultural areas and may have impacted groundwater sources used by local communities.

The pollution board also stated that corrective measures previously recommended to the company had not been fully implemented, prompting authorities to seek further clarification on the matter.

Tata denies violations

Tata Electronics has rejected allegations of non-compliance and said it had undertaken an independent assessment through an accredited laboratory. According to the company, the analysis found that its operations were in line with applicable environmental regulations.

The company reiterated its commitment to responsible manufacturing practices and environmental stewardship, adding that it has responded to the concerns raised by regulatory authorities.

The TNPCB has asked Tata Electronics to explain why stricter action should not be initiated, including possible suspension of power supply and closure of the facility if violations are established.

Neither Apple nor the Tamil Nadu government has publicly commented on the matter.

The development comes as India continues to strengthen its position as a global electronics manufacturing destination. With increasing investments from multinational technology companies, environmental compliance and sustainable industrial practices are expected to remain key areas of regulatory focus across the sector.
